Kant held that the issue of causality does not apply among dinge an sich (things in themselves) and in fact Physics is formulated in such a way that things know to move to lower energy levels [the Lagrange formulation]. So even though causality is true, it seems that physics is in fact showing that in a deeper sense causality is not fundamental. 

So even though causality is true and even true locally, still the general way Physics is formulated nowadays with idea of things tending towards lower energy levels, [and how would that poor electron know about that?] shows that there is some level of reality that is transcendent

(things in themselves) means things without the characteristics that we the observers attribute to them. That is: the way they are without our contribution.
